Installing PIL was no problem, but I couldn’t import it.
I used homebrew, PIP, easy_install, they all say it’s correctly installed in the various directories.
I just decided to fix it by going to /Library/Python/2.6/site-packages and making a symlink from the egg file to to PIL
cd /Library/Python/2.6/site-packages ln -s PIL-1.1.7-py2.6-macosx-10.6-universal.egg/ PIL
I suggest you not dwell on it and do this instead.
